The penicillin biosynthetic genes (pcbAB, pcbC, penDE) of Penicillium chrysogenum AS-P-78 were located in a 106.5-kb DNA region that is amplified in tandem repeats (five or six copies) linked by conserved TTTACA sequences. The wild-type strains P. chrysogenum NRRL 1951 and Penicillium notatum ATCC 9478 (Fleming's isolate) contain a single copy of the 106.5-kb region. This region was bordered by the same TTTACA hexanucleotide found between tandem repeats in strain AS-P-78. A penicillin overproducer strain, P. chrysogenum E1, contains a large number of copies in tandem of a 57.9-kb DNA fragment, linked by the same hexanucleotide or its reverse complementary TGTAAA sequence. The deletion mutant P. chrysogenum npe10 showed a deletion of 57.9 kb that corresponds exactly to the DNA fragment that is amplified in E1. The conserved hexanucleotide sequence was reconstituted at the deletion site. The amplification has occurred within a single chromosome (chromosome I). The tandem reiteration and deletion appear to arise by mutation-induced site-specific recombination at the conserved hexanucleotide sequences.

Carlos Vázquez-SalinasThe present study is an overview of the role of vegetables as a transmission vehicle of Salmonella in Mexico. One hundred samples of each of 17 different vegetables were analyzed during a period of 18 months. Salmonella was isolated from 98 samples. Salmonella enterica serovar Typhimurium was isolated from the highest percentage of samples with typeable Salmonella isolates (23.9%), followed by S. enterica subsp. arizonae and Salmonella Choleraesuis each from 16.9%, Salmonella Gallinarum from 11.1%, Salmonella Anatum and S. enterica subsp. houtenae each from 9.7%, Salmonella Agona and Salmonella Edinburg each from 4.22%, Salmonella Enteritidis and S. enterica subsp. salamae each from 2.81%, and Salmonella Bongor, Salmonella Pullorum, Salmonella Typhi, and Salmonella C1 flagellar b each from 1.4%. Of the isolated bacteria, 27.6% were nontypeable strains. Salmonella was isolated from 12% of parsley samples, 11% of cilantro samples, 9% of broccoli samples, 9% of cauliflower samples, 9% of “papaloquelite” (Por...

Francisco José Fernández Perrino has served as a professor in the Department of Biotechnology at the Universidad Autónoma Metropolitana (UAM) Iztapalapa Campus since 2000. He received his Ph.D. in Biology from the University of León (Spain), and he obtained, in 1999, the Extraordinary Doctorate Award from the Faculty of Biology of the University of León (Spain). He has received, on five
occasions (2003, 2005, 2005, 2007, 2014, and 2016), the Teaching Award and two (2005 and 2012) Research Awards from the Division of Biological and Health Sciences (Iztapalapa Campus). In 2024, he received the Medal for Academic Merit from the Metropolitan Autonomous University. He has been a Mexican Academy of Sciences member and has belonged to the National System of Researchers of Mexico (Level II) since July 2001. Likewise, he has been a member of the expert base of the National Agency of Evaluation and Prospective (ANEP), Spain, since February 2016. Regarding research, his interests are focused on thegenetic engineering of industrial microorganisms, as well as obtaining compounds of interest using microorganisms.
